Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of silo rescue, and in particular relates to a silo quick rescue device and a use method thereof. Background Art
[0002] In the maintenance of liquid solid materials such as silos, granaries, rice silos, and lime powder silos, due to the properties of liquid materials, once a person falls in, there is no force point, and once they fall in, they cannot get up by themselves, and rescue is extremely difficult. Due to the liquid properties of materials, when digging on one side, the materials next to it will automatically flow and gather to bury the person, and the burial time will cause great pressure on the heart and lungs of the trapped person if it is too long. If buried for a long time, it will cause the trapped person to suffocate and die. Therefore, the rescue of people trapped in silos has always been a top priority. Since the person to be rescued is trapped in the liquid material and is under the pressure of the material, if the person to be rescued is forcibly dragged, it may cause damage beyond the body's ability to bear.
[0003] Crane is the common name for cranes such as cranes, overhead cranes, and overhead cranes. Cranes are basically the same as what we call cranes. There are basically two types of crane drive methods: one is centralized drive, that is, a motor drives a long transmission shaft to drive the active wheels on both sides; the other is separate drive, that is, the active wheels on both sides are driven by a motor. Medium and small bridge cranes mostly use a "three-in-one" drive method that combines brakes, reducers and motors into one. For the convenience of installation and adjustment of ordinary bridge cranes with large lifting capacity, universal couplings are often used in the drive device.
[0004] Screw conveyor, commonly known as auger, is a kind of conveying equipment widely used in mining, feed, grain and oil, and construction industries. From the perspective of the displacement direction of the conveyed materials, screw conveyors are divided into two types: horizontal screw conveyors and vertical screw conveyors. They are mainly used for horizontal conveying and vertical lifting of various loose materials such as powders, granules and small blocks.
[0005] The shortcomings of the existing technology are that, due to the environment of the fluid material in the silo, it is impossible to directly dig up the material for rescue during rescue, which makes rescue difficult, and rescue workers need to be on the material to carry out construction, which is highly dangerous and has low rescue efficiency. Summary of the invention

The openings at the bottom and top of the material isolation cylinder are used for people to pass through. The driving mechanism of the discharge mechanism is used to drive the feed screw to rotate, thereby moving the material at the feed inlet in the material isolation cylinder to the discharge outlet for discharge until the material height is lowered to the point where the rescued persons can move.
[0009] Furthermore, the lifting equipment includes a crane arranged in the silo, and the crane is electrically connected to a manipulator.
[0010] The movement of the crane and the lowering of the material isolation cylinder are controlled by the controller, eliminating the need for rescue workers to carry and move the material on site, thus reducing the risks for rescue workers.
[0011] Furthermore, the material isolation cylinder is provided with a sinking mechanism for sinking the material isolation cylinder into the material, and the sinking mechanism is electrically connected to the manipulator.
[0012] The material isolation cylinder and the discharge mechanism are sunk into the material through the sinking mechanism, and the action of the sinking mechanism is remotely controlled by the controller. There is no need for personnel to stand on the material pile to operate, which is highly safe.
[0013] Furthermore, the sinking mechanism includes a driving motor 1, and the driving motor 1 is connected to an eccentric block.
[0014] The eccentric block is driven to rotate by a driving motor, so that the material isolation cylinder is shaken and the material isolation cylinder is sunk downward.
[0015] Furthermore, the sinking mechanism includes a mounting seat, a lifting member is provided on the mounting seat, and the lifting member is connected to a heavy hammer for cooperating with the bottom of the mounting seat.
[0016] After the heavy hammer is lifted by the lifting member, the heavy hammer falls freely and impacts the bottom of the mounting seat, driving the material isolation cylinder to sink as a whole.
[0017] Furthermore, the lifting member includes a second driving motor, a lifting drum is provided at the output end of the second driving motor, a lifting guide groove is provided on the lifting drum, the lifting guide groove includes a spiral groove and a vertical groove, a connecting rod is connected to the top of the weight, a guide rod is connected to the connecting rod, the guide rod is slidably connected in the lifting guide groove, and a vertical sliding groove for cooperating with the guide rod is provided on the mounting seat.
[0018] The lifting drum is driven to rotate by driving motor 2, and the connecting rod and the heavy hammer are lifted by cooperating with the spiral groove of the lifting guide groove and the guide rod. When lifted to the top, the guide rod falls from the vertical groove, and the bottom of the heavy hammer impacts the bottom of the mounting seat, driving the material isolation cylinder to sink.
[0019] Furthermore, the support mechanism includes a plurality of rib structures arranged on the inner wall of the material isolation cylinder, and the plurality of rib structures are distributed along the height direction.

[0029] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. In the description of the present invention, it should be noted that the terms front, back, left, right, etc. indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, or the directions or positional relationships in which the product is usually placed when in use. They are only for the convenience of describing the present invention or simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Example 1
[0030] like Figure 1-2 As shown, a silo quick rescue device includes a material isolation cylinder 1, the bottom and top of the material isolation cylinder 1 are provided with openings 2, the material isolation cylinder 1 is provided with lifting ears 3 for connecting lifting equipment, a discharge mechanism is provided in the material isolation cylinder 1, the discharge mechanism includes a feed pipe 4 and a driving mechanism, a feed screw is provided in the middle of the feed pipe 4, the feed screw is connected to the driving mechanism, a feed port 5 is provided at the bottom end of the feed pipe 4, a discharge port 6 facing the outside of the material isolation cylinder 1 is provided at the upper part of the feed pipe 4, and a support mechanism for people to grasp or stand is provided in the material isolation cylinder 1.
[0031] In the above scheme, a lifting ear 3 is provided on the material isolation cylinder 1 to connect the lifting equipment. The material isolation cylinder 1 is moved by the lifting equipment, and the material isolation cylinder 1 is placed on the outer circle of the person to be rescued to prevent the material from flowing inward. The openings 2 at the bottom and top of the material isolation cylinder 1 are used for people to pass through, and the driving mechanism of the discharge mechanism is used to drive the feed screw to rotate, thereby moving the material at the feed port 5 in the material isolation cylinder 1 to the discharge port 6 for discharge until the material height is reduced to the point where the person to be rescued can move.
[0032] At least three lifting ears 3 are arranged equidistantly along the outer ring of the material isolation cylinder 1. The discharge mechanism is fixed to the inner side of the material isolation cylinder 1 by bolts, and multiple discharge mechanisms can be arranged along the inner ring of the material isolation cylinder 1 to improve the discharge efficiency.
[0033] Furthermore, the hoisting equipment includes a crane 7 disposed in the silo, and the crane 7 is electrically connected to a controller.
[0034] The crane 7 is controlled by a manipulator to move and lower the material isolation cylinder 1, eliminating the need for rescue workers to carry and move the material on site, thereby reducing the risk of rescue workers.
[0035] The manipulator is arranged at the inlet and outlet of the silo.
[0036] Further, the support mechanism includes a plurality of rib structures 21 provided on the inner wall of the material isolation cylinder 1, and the plurality of rib structures 21 are distributed in the height direction.
[0037] By providing the rib structures 21, it is for the rescued person to grasp and prevent the body from sinking further. When the rescued person breaks away from the material, they can step on and support on the rib structures 21 and be transferred to the inlet and outlet of the silo together with the device.
[0038] The rib structure 21 is a U-shaped structure, and a plurality of groups of rib structures 21 are provided along the circumferential direction of the inner wall of the conveying pipe 4.
[0039] Further, the conveying screw includes a rotating shaft 22 and a spiral blade 23 provided on the rotating shaft 22, and a tip 24 is provided at the bottom end of the conveying pipe 4.
[0040] The rotation of the spiral blade 23 is driven by the rotating shaft 22 to achieve the conveying of the material. The bottom end of the conveying pipe 4 is provided as the tip 24, which is convenient for inserting into the material together with the material isolation cylinder 1.
[0041] Further, the driving mechanism includes a driving motor three 8 and / or a rotating handle 13, and a standing support part 25 is provided on the outer side of the material isolation cylinder 1.
[0042] The rotation of the conveying screw is driven by the driving motor three 8 to achieve the conveying of the material. The rotating handle 13 can manually rotate the conveying screw to work in an emergency, and the standing support part 25 is provided for people to stand on.
[0043] The standing support part 25 can be a U-shaped metal structure, or a columnar structure, or a perforated plate. The rotating handle 13 is传动连接 to the conveying screw through a gear mechanism.
[0044] It should be noted that the phrase "传动连接" in the original text seems to be a misspelling. It might be "drivably connected" or "transmission connection" in a more accurate context. Here, I've just translated it as "传动连接" as per the requirement to keep the original text unchanged. If there's an error in the original, it should be corrected for a more accurate translation.There are two ways to drive the discharge mechanism. One is to turn the handle 13 and turn the spiral worm by hand to bring out the material inside the material isolation tube 1. The mechanical drive can adapt to all working conditions and is not restricted by water, electricity, and wind. The use of the drive motor 38 is faster and more efficient. Both methods can be used here to realize the material taking function and take out the material inside the material isolation tube 1. After the material inside the material isolation tube 1 is taken out, the material isolation tube 1 forms a separate isolation space. The material inside the material isolation tube 1 is taken out, and the rescue personnel next to it can pull the trapped person out to achieve rescue. If it is a material with very strong fluidity, we can install a hanging point, hang the material isolation tube 1, place it to sink as a whole, and then start the rescue. After a part of the material inside the material isolation tube 1 is taken out, the trapped person is put on a safety belt and lifted out. Then the rescue personnel stand on the grid plate of the material isolation tube 1 and rescue the rescue personnel synchronously by lifting out the material isolation tube 1. This method can not only rescue the trapped person, but also ensure the safety of the rescue personnel.
[0045] A method for using the above-mentioned silo rapid rescue device includes the following steps: moving the material isolation cylinder 1 to the top of the person to be rescued by means of a lifting device, lowering the material isolation cylinder 1, inserting the material isolation cylinder 1 into the material outside the person to be rescued by means of manual force or the operation of a sinking mechanism, and operating a discharge mechanism to discharge the material inside the material isolation cylinder 1 out of the material isolation cylinder 1 until the material height is lowered to a level that the person to be rescued can move.
[0046] In the above scheme, the material isolation cylinder 1 is moved by lifting equipment without manual operation and is highly safe. After the material isolation cylinder 1 is inserted into the outer circle of the person to be rescued, the discharge mechanism discharges the material inside the material isolation cylinder 1 to rescue the person to be rescued in the material. The rescue is convenient and safe. Example 2
[0047] like Figure 3 As shown, a silo quick rescue device of this embodiment is further optimized on the basis of embodiment 1: Furthermore, the material isolation cylinder 1 is provided with a sinking mechanism for sinking the material isolation cylinder 1 into the material, and the sinking mechanism is electrically connected to the manipulator.
[0048] The material isolation cylinder 1 and the discharging mechanism are sunk into the material through the sinking mechanism, and the action of the sinking mechanism is remotely controlled through the controller. There is no need for personnel to stand on the material pile to operate, and the safety is high.
[0049] Furthermore, the sinking mechanism includes a driving motor 9, and the driving motor 9 is connected to an eccentric block 11.
[0050] The eccentric block 11 is driven to rotate by a driving motor 9, so that the material isolation cylinder 1 is shaken and the material isolation cylinder 1 is sunk downward.
[0051] The driving motors 9 are symmetrically distributed on the outer ring of the material isolation cylinder 1. In the embodiment, two driving motors 9 are arranged opposite to each other. A cylindrical housing 26 is arranged at both ends of the driving motor 9, and the eccentric block 11 is arranged in the cylindrical housing 26. Example 3
[0052] like Figure 4-6 As shown, a silo quick rescue device and a method of use of this embodiment are further optimized on the basis of embodiment 1: Furthermore, the material isolation cylinder 1 is provided with a sinking mechanism for sinking the material isolation cylinder 1 into the material, and the sinking mechanism is electrically connected to the manipulator.
[0053] The material isolation cylinder 1 and the discharging mechanism are sunk into the material through the sinking mechanism, and the action of the sinking mechanism is remotely controlled through the controller. There is no need for personnel to stand on the material pile to operate, and the safety is high.
[0054] Furthermore, the sinking mechanism includes a mounting seat 12 , and a lifting member is provided on the mounting seat 12 . The lifting member is connected to a heavy hammer 17 for cooperating with the bottom of the mounting seat 12 .
[0055] After the weight 17 is lifted by the lifting member, the weight 17 is allowed to fall freely and impact the bottom of the mounting seat 12, driving the material isolation cylinder 1 to sink as a whole.
[0056] The hoist may include a conventional drive motor that drives the wire rope and the weight 17 through a wire wheel to drive the weight 17 to continuously perform free fall motion, thereby achieving downward impact movement of the material isolation cylinder 1. The mounting seat 12 is symmetrically arranged on the outside of the material isolation cylinder 1.
[0057] Furthermore, the lifting member includes a driving motor 10, and a lifting drum 14 is provided at the output end of the driving motor 10. A lifting guide groove is provided on the lifting drum 14, and the lifting guide groove includes a spiral groove 15 and a vertical groove 16.

The guide rod 19 is slidably connected in the lifting guide groove, and a vertical sliding groove 20 for cooperating with the guide rod 19 is provided on the mounting seat 12.
[0058] The lifting drum 14 is driven to rotate by the driving motor 2 10, and the connecting rod 18 and the weight 17 are lifted by the spiral groove 15 of the lifting guide groove and the guide rod 19. When lifted to the top, the guide rod 19 falls from the vertical groove 16, and the bottom of the weight 17 impacts the bottom of the mounting seat 12, driving the material isolation cylinder 1 to sink. The vertical slide groove 20 is used to guide and limit the guide rod 19 vertically.
[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
